As with all mutual funds, the Securities and Exchange Commission has not approved or disapproved these securities or passed upon the adequacy of this prospectus. Any representation to the contrary is a criminal offense.

To seek total return with an emphasis on current income as well as capital appreciation.

This table describes the fees and expenses you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts on Class A shares if you and your family invest, or agree to invest in the future, at least $100,000 in the John Hancock family of funds. More information about these and other discounts is available from your financial representative and on pages 22 to 24 of the prospectus under "Sales charge reductions and waivers" or pages 204 to 208 of the fund's Statement of Additional Information under "Initial sales charge on Class A shares."

2 The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund, in an amount equal to the amount by which expenses of the fund exceed 0.78% of average net assets. For purposes of this agreement, "expenses of the fund" means all fund expenses, excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (e) class-specific expenses, (f) acquired fund fees and expenses paid indirectly, (g) borrowing costs, (h) prime brokerage fees, and (i) short dividend expense. This agreement expires on December 31, 2017, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

3 The distributor contractually agrees to waive and limit its Rule 12b-1 fees for Class R4 shares to the extent necessary to achieve aggregate fees paid to the distributor of 0.15%. This agreement expires on December 31, 2017, unless renewed by mutual agreement of the fund and the distributor based upon a determination that this is appropriate under the circumstances at that time.

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During its most recent fiscal year, the fund's portfolio turnover rate was 26% of the average value of its portfolio.

Under normal market conditions, the fund invests at least 80% of its net assets in fixed-income securities and debt instruments of emerging-market issuers. The manager may consider, but is not limited to, the classifications by the World Bank, the International Finance Corporations, or the United Nations and its agencies in determining whether a country is an emerging or a developed country. Examples of emerging-market countries include most African, Central Asian, Eastern European, and South and Central American nations.

The manager uses proprietary research to identify specific countries, corporate sectors, and issuers that are attractively priced. The manager's investment decisions are not constrained by market capitalization, company fundamentals, security valuation or seasoning, or similar characteristics. The manager uses economic and industry analysis to try to anticipate shifts in the business cycle. Due to potentially volatile conditions in emerging markets, the fund's portfolio turnover ratio may be higher-than-average, which could increase transaction costs.

The fund may invest in debt securities of any maturity denominated in any currency, including but not limited to: debt issued by governments or government agencies, including the U.S. Treasury; U.S. and foreign corporate-debt instruments; mortgage- and asset-backed securities and collateralized mortgage obligations; and variable and floating-rate senior and subordinated corporate-debt obligations. The fund may invest in countries that do not have sovereign bond ratings or whose bonds are rated below-investment-grade (junk bonds). The fund may invest in corporate or other privately issued debt instruments of issuers with market capitalizations below $1 billion. The fund may attempt to mitigate the risk of unexpected, adverse currency fluctuations through the use of exchange-listed or over-the-counter financial derivatives instruments, including currency forwards, nondeliverable forwards, currency options, interest-rate swaps, interest-rate futures, interest-rate options, index options, and credit default swaps.

The fund is non-diversified and may both concentrate its assets in a smaller number of issuers and invest more of its assets in the securities of a single issuer than a diversified fund.

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. The fund's investment strategy may not produce the intended results.

During periods of heightened market volatility or reduced liquidity, governments, their agencies, or other regulatory bodies, both within the United States and abroad, may take steps to intervene. These actions, which could include legislative, regulatory, or economic initiatives, might have unforeseeable consequences and could adversely affect the fund's performance or otherwise constrain the fund's ability to achieve its investment objective.

The fund's main risks are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

Changing distribution levels risk. The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.

Credit and counterparty risk. The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund's securities could affect the fund's performance.

Cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance.

Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.

Emerging-market risk. The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.

Fixed-income securities risk. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security's credit quality may adversely affect fund performance.

investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts and swaps, futures contracts, interest-rate swaps, and options. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.

High portfolio turnover risk. Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.

Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.

Lower-rated and high-yield fixed-income securities risk. Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.

Mortgage-backed and asset-backed securities risk. Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks.

Non-diversified risk. Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.

Sector risk. When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors.

Small and mid-sized company risk. Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.

The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year compared with a broad-based market index. Past performance (before and after taxes) does not indicate future results. All figures assume dividend reinvestment. Performance information is updated daily, monthly, and quarterly and may be obtained at our website, jhinvestments.com, or by calling 800-225-5291, Monday to Thursday, 8:00 A.M.—7:00 P.M., and Friday, 8:00 A.M.—6:00 P.M., Eastern time (Class A and Class C), or 888-972-8696 between 8:30 A.M. and 5:00 P.M., Eastern time, on most business days (Class I, Class R2, Class R4, and Class R6).

Class A and Class C shares commenced operations on January 4, 2010 and August 28, 2014, respectively. Class R2, Class R4, and Class R6 shares commenced operations on March 27, 2015. Returns prior to a class's commencement date are those of Class A shares that have been recalculated to apply the gross fees and expenses of that class. Returns for Class C, Class R2, Class R4, and Class R6 shares would have been substantially similar to returns of Class A shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Please note that after-tax returns (shown for Class A shares only) reflect the highest individual federal marginal income-tax rate in effect as of the date provided and do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k), or other tax-advantaged investment plan. After-tax returns for other share classes would vary.

There are no minimum initial investment requirements for Class R2 or Class R4 shares. The minimum initial investment requirement for Class R6 shares is $1 million, except that there is no minimum for: qualified and nonqualified plan investors that do not require the fund or its affiliates to pay any type of administrative payment; Trustees; employees of the advisor or its affiliates; or members of the fund's portfolio management team. There are no subsequent minimum investment requirements for any of these share classes.

Class A, Class C, Class I and Class R6 shares may be redeemed on any business day by mail: John Hancock Signature Services, Inc., P.O. Box 55913, Boston, Massachusetts 02205-5913; or for most account types through our website: jhinvestments.com; or by telephone: 800-225-5291 (Class A and Class C); 888-972-8696 (Class I and Class R6). Class R2 and Class R4 shares may be redeemed on any business day by contacting your retirement plan administrator or recordkeeper.

The fund's distributions are taxable, and will be taxed as ordinary income and/or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or individual retirement account. Withdrawals from such tax-deferred arrangements may be subject to tax at a later date.

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, registered investment advisor, financial planner, or retirement plan administrator), the fund and its related companies may pay the broker-dealer or other intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. These payments are not applicable to Class R6 shares. Ask your salesperson or visit your financial intermediary's website for more information.

Investment objective: To seek total return with an emphasis on current income as well as capital appreciation.

The Board of Trustees can change the fund's investment objective and strategies without shareholder approval. The fund will provide written notice to shareholders at least 60 days prior to a change in its 80% investment policy.

Under normal market conditions, the fund invests at least 80% of its net assets in fixed-income securities and debt instruments of emerging-market issuers. The manager may consider, but is not limited to, the classifications by the World Bank, the International Finance Corporation, or the United Nations and its agencies in determining whether a country is an emerging or a developed country. Examples of emerging-market countries include most African, Central Asian, Eastern European, and South and Central American nations.

The portfolio managers use proprietary research to identify specific countries, corporate sectors, and issuers that are attractively priced, and shall not be constrained by market capitalization, company fundamentals, security valuation or seasoning, or similar characteristics. The portfolio managers use economic and industry analysis to try to anticipate shifts in the business cycle and determine which countries and sectors might benefit over the next 12 months. Due to potentially volatile conditions in emerging markets, the fund's investment process may result in a higher-than-average portfolio turnover ratio, which could increase transaction costs. In the event of extreme market conditions, the managers may temporarily depart from the investment strategy for defensive purposes.

A number of countries that the fund will invest in may not have sovereign ratings, may be below-investment-grade, or may be unrated. Below-investment-grade debt securities are also referred to as junk bonds. The fund may invest in corporate or other privately issued debt instruments of issuers having market capitalizations of below $1 billion at the time of investment. The debt securities in which the fund may invest include, but are not limited to, debt issued by governments or government agencies, including the U.S. Treasury; U.S. and foreign corporate-debt instruments; mortgage- and asset-backed securities and collateralized mortgage obligations; and variable and floating-rate senior and subordinated corporate-debt obligations. There is no limit on the maturities of the debt instruments in which the fund will invest. The fund may invest in securities denominated in any currency, including U.S. dollar-denominated emerging-market debt, and may be subject to unexpected, adverse currency fluctuations. The fund may attempt to mitigate the risk of unintended currency fluctuations through the use of exchange-listed or over-the-counter financial derivatives instruments, including currency forwards, nondeliverable forwards, currency options, interest-rate swaps, interest-rate futures, interest-rate options, index options, and credit default swaps.

Total return, commonly understood as the combination of income and capital appreciation, includes interest, capital gains, dividends, and distributions realized over a given period of time.

The fund may invest in cash or money market instruments for the purpose of meeting redemption requests or making other anticipated cash payments.

The fund may invest up to 100% of its assets in cash, money market instruments, or other investment-grade short-term securities for the purpose of protecting the fund in the event the manager determines that market, economic, political, or other conditions warrant a defensive posture.

To the extent that the fund is in a defensive position, its ability to achieve its investment objective will be limited.

The fund may lend its securities so long as such loans do not represent more than 33⅓% of the fund's total assets. The borrower will provide collateral to the lending portfolio so that the value of the loaned security will be fully collateralized. The collateral may consist of cash, cash equivalents, or securities issued or guaranteed by the U.S. government or its agencies or instrumentalities. The borrower must also agree to increase the collateral if the value of the loaned securities increases. As with other extensions of credit, there are risks of delay in recovery or even loss of rights in the collateral should the borrower of the securities fail financially.

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance. The fund's investment strategy may not produce the intended results.

Instability in the financial markets has led many governments, including the U.S. government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state, and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective. In addition, political events within the United States and abroad, including the U.S. government's ongoing difficulty agreeing on a long-term budget and deficit reduction plan and uncertainty surrounding sovereign debt of European Union members, could negatively impact financial markets and the fund's performance. Further, certain municipalities of the United States and its territories are financially strained and may face the possibility of default on their debt obligations, which could directly or indirectly detract from the fund's performance.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation, and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

factors that are not discussed in this prospectus because they are not considered primary factors, see the fund's Statement of Additional Information (SAI).

The distribution amounts paid by the fund generally depend on the amount of income and/or dividends paid by the fund's investments. As a result of market, interest rate and other circumstances, the amount of cash available for distribution by the fund and the fund's distribution rate may vary or decline. The risk of such variability is accentuated in currently prevailing market and interest rate circumstances.

This is the risk that the issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter (OTC) derivatives contract (see "Hedging, derivatives, and other strategic transactions risk"), or a borrower of a fund's securities will be unable or unwilling to make timely principal, interest, or settlement payments, or otherwise honor its obligations. Credit risk associated with investments in fixed-income securities relates to the ability of the issuer to make scheduled payments of principal and interest on an obligation. A fund that invests in fixed-income securities is subject to varying degrees of risk that the issuers of the securities will have their credit ratings downgraded or will default, potentially reducing the fund's share price and income level. Nearly all fixed-income securities are subject to some credit risk, which may vary depending upon whether the issuers of the securities are corporations, domestic or foreign governments, or their subdivisions or instrumentalities. U.S. government securities are subject to varying degrees of credit risk depending upon whether the securities are supported by the full faith and credit of the United States; the ability to borrow from the U.S. Treasury; only by the credit of the issuing U.S. government agency, instrumentality, or corporation; or otherwise supported by the United States. For example, issuers of many types of U.S. government securities (e.g., the Federal Home Loan Mortgage Corporation (Freddie Mac), Federal National Mortgage Association (Fannie Mae), and Federal Home Loan Banks), although chartered or sponsored by Congress, are not funded by congressional appropriations, and their fixed-income securities, including asset-backed and mortgage-backed securities, are neither guaranteed nor insured by the U.S. government. An agency of the U.S. government has placed Fannie Mae and Freddie Mac into conservatorship, a statutory process with the objective of returning the entities to normal business operations. It is unclear what effect this conservatorship will have on the securities issued or guaranteed by Fannie Mae or Freddie Mac. As a result, these securities are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States (e.g., U.S. Treasury bonds). When a fixed-income security is not rated, a manager may have to assess the risk of the security itself. Asset-backed securities, whose principal and interest payments are supported by pools of other assets, such as credit card receivables and automobile loans, are subject to further risks, including the risk that the obligors of the underlying assets default on payment of those assets.

Funds that invest in below-investment-grade securities, also called junk bonds (e.g., fixed-income securities rated Ba or lower by Moody's Investors Service, Inc. or BB or lower by Standard & Poor's Ratings Services, at the time of investment, or determined by a manager to be of comparable quality to securities so rated) are subject to increased credit risk. The sovereign debt of many foreign governments, including their subdivisions and instrumentalities, falls into this category. Below-investment-grade securities offer the potential for higher investment returns than higher-rated securities, but they carry greater credit risk: Their issuers' continuing ability to meet principal and interest payments is considered speculative, they are more susceptible to real or perceived adverse economic and competitive industry conditions, and they may be less liquid than higher-rated securities.

In addition, a fund is exposed to credit risk to the extent that it makes use of OTC derivatives (such as forward foreign currency contracts and/or swap contracts) and engages to a significant extent in the lending of fund securities or the use of repurchase agreements. OTC derivatives transactions can be closed out with the other party to the transaction. If the counterparty defaults, a fund will have contractual remedies, but there is no assurance that the counterparty will be able to meet its contractual obligations or that, in the event of default, a fund will succeed in enforcing them. A fund, therefore, assumes the risk that it may be unable to obtain payments owed to it under OTC derivatives contracts or that those payments may be delayed or made only after the fund has incurred the costs of litigation. While the manager intends to monitor the creditworthiness of contract counterparties, there can be no assurance that the counterparty will be in a position to meet its obligations, especially during unusually adverse market conditions.

Intentional cybersecurity breaches include unauthorized access to systems, networks, or devices (such as through "hacking" activity); infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. In addition, unintentional incidents can occur, such as the inadvertent release of confidential information (possibly resulting in the violation of applicable privacy laws).

A cybersecurity breach could result in the loss or theft of customer data or funds, the inability to access electronic systems ("denial of services"), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or costs associated with system repairs. Such incidents could cause a fund, the advisor, a manager, or other service providers to incur regulatory penalties, reputational damage, additional compliance costs, or financial loss. In addition, such incidents could affect issuers in which a fund invests, and thereby cause the fund's investments to lose value.

Events in the financials sector historically have resulted, and may result from time to time, in an unusually high degree of volatility in the financial markets, both domestic and foreign. These events have included, but are not limited to: bankruptcies, corporate restructurings, and other events related to the sub-prime mortgage crisis in 2008; financial distress in the U.S. auto industry; credit and liquidity issues involving certain money market mutual funds; governmental efforts to limit short selling and high frequency trading; measures to address U.S. federal and state budget deficits; social, political, and economic instability in Europe; Standard & Poor's Ratings Services' downgrade of U.S. long-term sovereign debt; economic stimulus by the Japanese central bank; steep declines in oil prices; dramatic changes in currency exchange rates; and China's economic slowdown. Global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region might adversely impact issuers in a different country or region. Both domestic and foreign equity markets have experienced increased volatility and turmoil, with issuers that have exposure to the real estate,

mortgage, and credit markets particularly affected, and it is uncertain when these conditions will recur. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

In addition to financial market volatility, relatively high market volatility and reduced liquidity in credit and fixed-income markets may adversely affect many issuers worldwide. Actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, such as decreases or increases in short-term interest rates, or interventions in currency markets, could cause high volatility in the equity and fixed-income markets. This reduced liquidity may result in less money being available to purchase raw materials, goods, and services from emerging markets, which may, in turn, bring down the prices of these economic staples. It may also result in emerging-market issuers having more difficulty obtaining financing, which may, in turn, cause a decline in their securities prices. These events and the possible resulting market volatility may have an adverse effect on the fund.

Political turmoil within the United States and abroad may also impact the fund. Although the U.S. government has honored its credit obligations, it remains possible that the United States could default on its obligations. While it is impossible to predict the consequences of such an unprecedented event, it is likely that a default by the United States would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of the fund's investments. Similarly, political events within the United States at times have resulted, and may in the future result, in a shutdown of government services, which could negatively affect the U.S. economy, decrease the value of many fund investments, and increase uncertainty in or impair the operation of the U.S. or other securities markets.

Uncertainties surrounding the sovereign debt of a number of European Union (EU) countries and the viability of the EU have disrupted and may in the future disrupt markets in the United States and around the world. If one or more countries leave the EU or the EU dissolves, the world's securities markets likely will be significantly disrupted. In June 2016, the United Kingdom approved a referendum to leave the EU, commonly referred to as "Brexit." There is significant market uncertainty regarding Brexit's ramifications, and the range and potential implications of possible political, regulatory, economic, and market outcomes are difficult to predict. Political and military events, including the military crises in Ukraine, Turkey, and the Middle East, and nationalist unrest in Europe, also may cause market disruptions.

In addition, there is a risk that the prices of goods and services in the U.S. and many foreign economies may decline over time, known as deflation. Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely. If a country's economy slips into a deflationary pattern, it could last for a prolonged period and may be difficult to reverse.

Fixed-income securities are generally subject to two principal types of risk, as well as other risks described below: (1) interest-rate risk and (2) credit quality risk.

Interest-rate risk. Fixed-income securities are affected by changes in interest rates. When interest rates decline, the market value of fixed-income securities generally can be expected to rise. Conversely, when interest rates rise, the market value of fixed-income securities generally can be expected to decline. The longer the duration or maturity of a fixed-income security, the more susceptible it is to interest-rate risk. Recent and potential future changes in government monetary policy may affect the level of interest rates.

Credit quality risk. Fixed-income securities are subject to the risk that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. If the credit quality of a fixed-income security deteriorates after a fund has purchased the security, the market value of the security may decrease and lead to a decrease in the value of the fund's investments. An issuer's credit quality could deteriorate as a result of poor management decisions, competitive pressures, technological obsolescence, undue reliance on suppliers, labor issues, shortages, corporate restructurings, fraudulent disclosures, or other factors. Funds that may invest in lower-rated fixed-income securities, commonly referred to as junk securities, are riskier than funds that may invest in higher-rated fixed-income securities. Additional information on the risks of investing in investment-grade fixed-income securities in the lowest rating category and lower-rated fixed-income securities is set forth below.

Prepayment of principal risk. Many types of debt securities, including floating-rate loans, are subject to prepayment risk. Prepayment risk occurs when the issuer of a security can repay principal prior to the security's maturity. Securities subject to prepayment risk can offer less potential for gains when the credit quality of the issuer improves.

Funds that invest in securities traded principally in securities markets outside the United States are subject to additional and more varied risks, as the value of foreign securities may change more rapidly and extremely than the value of U.S. securities. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. Additionally, issuers of foreign securities may not be subject to the same degree of regulation as U.S. issuers. Reporting, accounting, and auditing standards of foreign countries differ, in some cases significantly, from U.S. standards. There are generally higher commission rates on foreign portfolio transactions, transfer taxes, higher custodial costs, and the possibility that foreign taxes will be charged on dividends and interest payable on foreign securities, some or all of which may not be reclaimable. Also, for lesser-developed countries, nationalization, expropriation, or confiscatory taxation; adverse changes in investment or exchange control regulations (which may include suspension of the ability to transfer currency or assets from a country); political changes; or diplomatic developments could adversely affect a fund's investments. In the event of nationalization, expropriation, or other confiscation, the fund could lose its entire investment in a foreign security. All funds that invest in foreign securities are subject to these risks. Some of the foreign risks are also applicable to funds that invest a material portion of their assets in securities of foreign issuers traded in the United States.

Currency risk. Currency risk is the risk that fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active investment position, will decline in value relative to the U.S. dollar and, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly for a number of reasons, including the forces of supply and demand in the foreign exchange markets, actual or perceived changes in interest rates, and intervention (or the failure to intervene) by U.S. or foreign governments or central banks, or by currency controls or political developments in the United States or abroad. Certain funds may engage in proxy hedging of currencies by entering into derivative transactions with respect to a currency whose value is expected to correlate to the value of a currency the fund owns or wants to own. This presents the risk that the two currencies may not move in relation to one another as expected. In that case, the fund could lose money on its investment and also lose money on the position designed to act as a proxy hedge. Certain funds may also take active currency positions and may cross-hedge currency exposure represented by their securities into another foreign currency. This may result in a fund's currency exposure being substantially different from that suggested by its securities investments. All funds with foreign currency holdings and/or that invest or trade in securities denominated in foreign currencies or related derivative instruments may be adversely affected by changes in foreign currency exchange rates. Derivative foreign currency transactions (such as futures, forwards, and swaps) may also involve leveraging risk, in addition to currency risk. Leverage may disproportionately increase a fund's portfolio losses and reduce opportunities for gain when interest rates, stock prices, or currency rates are changing.

The ability of a fund to utilize hedging, derivatives, and other strategic transactions to benefit the fund will depend in part on its manager's ability to predict pertinent market movements and market risk, counterparty risk, credit risk, interest-rate risk, and other risk factors, none of which can be assured. The skills required to utilize hedging and other strategic transactions are different from those needed to select a fund's securities. Even if the manager only uses hedging and other strategic transactions in a fund primarily for hedging purposes or to gain exposure to a particular securities market, if the transaction does not have the desired outcome, it could result in a significant loss to a fund. The amount of loss could be more than the principal amount invested. These transactions may also increase the volatility of a fund and may involve a small investment of cash relative to the magnitude of the risks assumed, thereby magnifying the impact of any resulting gain or loss. For example, the potential loss from the use of futures can exceed a fund's initial investment in such contracts. In addition, these transactions could result in a loss to a fund if the counterparty to the transaction does not perform as promised.

A fund may invest in derivatives, which are financial contracts with a value that depends on, or is derived from, the value of underlying assets, reference rates, or indexes. Derivatives may relate to stocks, bonds, interest rates, currencies or currency exchange rates, and related indexes. A fund may use derivatives for many purposes, including for hedging and as a substitute for direct investment in securities or other assets. Derivatives may be used in a way to efficiently adjust the exposure of a fund to various securities, markets, and currencies without a fund actually having to sell existing investments and make new investments. This generally will be done when the adjustment is expected to be relatively temporary or in anticipation of effecting the sale of fund assets and making new investments over time. Further, since many derivatives have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the derivative itself. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. When a fund uses derivatives for leverage, investments in that fund will tend to be more volatile, resulting in larger gains or losses in response to market changes. To limit leverage risk, a fund may segregate assets determined to be liquid or, as permitted by applicable regulation, enter into certain offsetting positions to cover its obligations under derivative instruments. For a description of the various derivative instruments the fund may utilize, refer to the SAI.

The regulation of the U.S. and non-U.S. derivatives markets has undergone substantial change in recent years and such change may continue. In particular, the Dodd-Frank Wall Street Reform and Consumer Protection Act, and regulation proposed to be promulgated thereunder require many derivatives to be cleared and traded on an exchange, expand entity registration requirements, impose business conduct requirements on dealers that enter into swaps with a pension plan, endowment, retirement plan or government entity, and required banks to move some derivatives trading units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. Although the Commodity Futures Trading Commission (CFTC) has released final rules relating to clearing, reporting, recordkeeping and registration requirements under the legislation, many of the provisions are subject to further final rule making, and thus its ultimate impact remains unclear. New regulations could, among other things, restrict the fund's ability to engage in derivatives transactions (for example, by making certain types of derivatives transactions no longer available to the fund) and/or increase the costs of such derivatives transactions (for example, by increasing margin or capital requirements), and the fund may be unable to fully execute its investment strategies as a result. Limits or restrictions applicable to the counterparties with which the fund engages in derivative transactions also could prevent the fund from using these instruments or affect the pricing or other factors relating to these instruments, or may change the availability of certain investments.

At any time after the date of this prospectus, legislation may be enacted that could negatively affect the assets of the fund. Legislation or regulation may change the way in which the fund itself is regulated. The advisor cannot predict the effects of any new governmental regulation that may be implemented, and there can be no assurance that any new governmental regulation will not adversely affect the fund's ability to achieve its investment objectives.

The use of derivative instruments may involve risks different from, or potentially greater than, the risks associated with investing directly in securities and other, more traditional assets. In particular, the use of derivative instruments exposes a fund to the risk that the counterparty to an OTC derivatives contract will be unable or unwilling to make timely settlement payments or otherwise honor its obligations. OTC derivatives transactions typically can only be closed out with the other party to the transaction, although either party may engage in an offsetting transaction that puts that party in the same economic position as if it had closed out the transaction with the counterparty or may obtain the other party's consent to assign the transaction to a third party. If the counterparty defaults, the fund will have contractual remedies, but there is no assurance that the counterparty will meet its contractual obligations or that, in the event of default, the fund will succeed in enforcing them. For example, because the contract for each OTC derivatives transaction is individually negotiated with a specific counterparty, a fund is subject to the risk that a counterparty may interpret contractual terms (e.g., the definition of default) differently than the fund when the fund seeks to enforce its contractual rights. If that occurs, the cost and unpredictability of the legal proceedings required for the fund to enforce its contractual rights may lead it to decide not to pursue its claims against the counterparty. The fund, therefore, assumes the risk that it may be unable to obtain payments owed to it under OTC derivatives contracts or that those payments may be delayed or made only after the fund has incurred the costs of litigation. While a manager intends to monitor the creditworthiness of counterparties, there can be no assurance that a counterparty will meet its obligations, especially during unusually adverse market conditions. To the extent a fund contracts with a limited number of counterparties, the fund's risk will be concentrated and events that affect the creditworthiness of any of those counterparties may have a pronounced effect on the fund. Derivatives are also subject to a number of other risks, including market risk and liquidity risk. Since the value of derivatives is calculated and derived from the value of other assets, instruments, or references, there is a risk that they will be improperly valued. Derivatives also involve the risk that changes in their value may not correlate perfectly with the assets, rates, or indexes they are designed to hedge or closely track. Suitable derivatives transactions may not be available in all circumstances. The fund is also subject to the risk that the counterparty closes out the derivatives transactions upon the occurrence of certain triggering events. In addition, a manager may determine not to use derivatives to hedge or otherwise reduce risk exposure. Government legislation or regulation could affect the use of derivatives transactions and could limit a fund's ability to pursue its investment strategies.

A detailed discussion of various hedging and other strategic transactions appears in the SAI. The following is a list of certain derivatives and other strategic transactions that the fund intends to utilize and the main risks associated with each of them:

Credit default swaps. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, risk of default of the underlying reference obligation, and risk of disproportionate loss are the principal risks of engaging in transactions involving credit default swaps.

Foreign currency forward contracts. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), foreign currency risk, and risk of disproportionate loss are the principal risks of engaging in transactions involving foreign currency forward contracts.

Foreign currency swaps. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), foreign currency risk, and risk of disproportionate loss are the principal risks of engaging in transactions involving foreign currency swaps.

Futures contracts. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), and risk of disproportionate loss are the principal risks of engaging in transactions involving futures contracts.

Interest-rate swaps. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), interest-rate risk, and risk of disproportionate loss are the principal risks of engaging in transactions involving interest-rate swaps.

Options. Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), and risk of disproportionate loss are the principal risks of engaging in transactions involving options. Counterparty risk does not apply to exchange-traded options.

A high fund portfolio turnover rate (over 100%) generally involves correspondingly greater brokerage commission and tax expenses, which must be borne directly by a fund and its shareholders, respectively. The portfolio turnover rate of a fund may vary from year to year, as well as within a year.

The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

The capacity of traditional dealers to engage in fixed-income trading has not kept pace with the bond market's growth. As a result, dealer inventories of corporate bonds, which indicate the ability to "make markets," i.e., buy or sell a security at the quoted bid and ask price, respectively, are at or near historic lows relative to market size. Because market makers provide stability to fixed-income markets, the significant reduction in dealer inventories could lead to decreased liquidity and increased volatility, which may become exacerbated during periods of economic or political stress.

Lower-rated fixed-income securities are defined as securities rated below investment grade (such as Ba and below by Moody's Investors Service, Inc. and BB and below by Standard & Poor's Ratings Services) (also called junk bonds). The general risks of investing in these securities are as follows:

Risk to principal and income. Investing in lower-rated fixed-income securities is considered speculative. While these securities generally provide greater income potential than investments in higher-rated securities, there is a greater risk that principal and interest payments will not be made. Issuers of these securities may even go into default or become bankrupt.

Liquidity. The market for lower-rated fixed-income securities may have more limited trading than the market for investment-grade fixed-income securities. Therefore, it may be more difficult to sell these securities, and these securities may have to be sold at prices below their market value in order to meet redemption requests or to respond to changes in market conditions.

Dependence on manager's own credit analysis. While a manager may rely on ratings by established credit rating agencies, it will also supplement such ratings with its own independent review of the credit quality of the issuer. Therefore, the assessment of the credit risk of lower-rated fixed-income securities is more dependent on the manager's evaluation than the assessment of the credit risk of higher-rated securities.

Additional risks regarding lower-rated corporate fixed-income securities. Lower-rated corporate fixed-income securities (and comparable unrated securities) tend to be more sensitive to individual corporate developments and changes in economic conditions than higher-rated corporate fixed-income securities. Issuers of lower-rated corporate fixed-income securities may also be highly leveraged, increasing the risk that principal and income will not be repaid.

Additional risks regarding lower-rated foreign government fixed-income securities. Lower-rated foreign government fixed-income securities are subject to the risks of investing in foreign countries described under "Foreign securities risk." In addition, the ability and willingness of a foreign government to make payments on debt when due may be affected by the prevailing economic and political conditions within the country. Emerging-market countries may experience high inflation, interest rates, and unemployment, as well as exchange-rate fluctuations which adversely affect trade and political uncertainty or instability. These factors increase the risk that a foreign government will not make payments when due.

Mortgage-backed securities. Mortgage-backed securities represent participating interests in pools of residential mortgage loans, which are guaranteed by the U.S. government, its agencies, or its instrumentalities. However, the guarantee of these types of securities relates to the principal and interest payments, and not to the market value of such securities. In addition, the guarantee only relates to the mortgage-backed securities held by the fund and not the purchase of shares of the fund.

Mortgage-backed securities are issued by lenders, such as mortgage bankers, commercial banks, and savings and loan associations. Such securities differ from conventional debt securities, which provide for the periodic payment of interest in fixed amounts (usually semiannually) with principal payments at maturity or on specified dates. Mortgage-backed securities provide periodic payments which are, in effect, a pass through of the interest and principal payments (including any prepayments) made by the individual borrowers on the pooled mortgage loans. A mortgage-backed security will mature when all the mortgages in the pool mature or are prepaid. Therefore, mortgage-backed securities do not have a fixed maturity and their expected maturities may vary when interest rates rise or fall.

When interest rates fall, homeowners are more likely to prepay their mortgage loans. An increased rate of prepayments on the fund's mortgage-backed securities will result in an unforeseen loss of interest income to the fund as the fund may be required to reinvest assets at a lower interest rate. Because prepayments increase when interest rates fall, the prices of mortgage-backed securities do not increase as much as other fixed-income securities when interest rates fall.

When interest rates rise, homeowners are less likely to prepay their mortgage loans. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security. Therefore, the prices of mortgage-backed securities may decrease more than prices of other fixed-income securities when interest rates rise.

The yield of mortgage-backed securities is based on the average life of the underlying pool of mortgage loans. The actual life of any particular pool may be shortened by unscheduled or early payments of principal and interest. Principal prepayments may result from the sale of the underlying property, or the refinancing or foreclosure of underlying mortgages. The occurrence of prepayments is affected by a wide range of economic, demographic, and social factors, and, accordingly, it is not possible to accurately predict the average life of a particular pool. The actual prepayment experience of a pool of mortgage loans may cause the yield realized by the fund to differ from the yield calculated on the basis of the average life of the pool. In addition, if the fund purchases mortgage-backed securities at a premium, the premium may be lost in the event of early prepayment, which may result in a loss to the fund.

Prepayments tend to increase during periods of falling interest rates, while during periods of rising interest rates, prepayments are likely to decline. Monthly interest payments received by a fund have a compounding effect, which will increase the yield to shareholders as compared with debt obligations that pay interest semiannually. Because of the reinvestment of prepayments of principal at current rates, mortgage-backed securities may be less effective than U.S. Treasury bonds of similar maturity at maintaining yields during periods of declining interest rates. Also, although the value of debt securities may increase as interest rates decline, the value of these pass through types of securities may not increase as much, due to their prepayment feature.

Collateralized mortgage obligations (CMOs). A fund may invest in mortgage-backed securities called CMOs. CMOs are issued in separate classes with different stated maturities. As the mortgage pool experiences prepayments, the pool pays off investors in classes with shorter maturities first. By investing in CMOs, a fund may manage the prepayment risk of mortgage-backed securities. However, prepayments may cause the actual maturity of a CMO to be substantially shorter than its stated maturity.

Asset-backed securities. Asset-backed securities include interests in pools of debt securities, commercial or consumer loans, or other receivables. The value of these securities depends on many factors, including changes in interest rates, the availability of information concerning the pool and its structure, the credit quality of the underlying assets, the market's perception of the servicer of the pool, and any credit enhancement provided. In addition, asset-backed securities have prepayment risks similar to mortgage-backed securities.

Overall risk can be reduced by investing in securities from a diversified pool of issuers, while overall risk is increased by investing in securities of a small number of issuers. If a fund is not diversified within the meaning of the Investment Company Act of 1940, as amended (1940 Act), that means it is allowed to invest a large portion of assets in any one issuer or a small number of issuers, which may result in greater susceptibility to associated risks. As a result, credit, market, and other risks associated with a non-diversified fund's investment strategies or techniques may be more pronounced than for funds that are diversified.

When a fund's investments are focused in one or a few sectors of the economy, they are not as diversified as the investments of most mutual funds and are far less diversified than the broad securities markets. This means that focused funds tend to be more volatile than other mutual funds, and the values of their investments tend to go up and down more rapidly. In addition, a fund which invests in particular sectors is particularly susceptible to the impact of market, economic, regulatory, and other factors affecting those sectors. From time to time, a small number of companies may represent a large portion of a particular sector or sectors.

Market risk and liquidity risk may be pronounced for securities of companies with medium-sized market capitalizations and are particularly pronounced for securities of companies with smaller market capitalizations. These companies may have limited product lines, markets, or financial resources, or they may depend on a few key employees. The securities of companies with medium and smaller market capitalizations may trade less frequently and in lesser volume than more widely held securities, and their value may fluctuate more sharply than those securities. They may also trade in the OTC market or on a regional exchange, or may otherwise have limited liquidity. Investments in less-seasoned companies with medium and smaller market capitalizations may not only present greater opportunities for growth and capital appreciation, but also involve greater risks than are customarily associated with more established companies with larger market capitalizations. These risks apply to all funds that invest in the securities of companies with smaller- or medium-sized market capitalizations. For purposes of the fund's investment policies, the market capitalization of a company is based on its capitalization at the time the fund purchases the company's securities. Market capitalizations of companies change over time. The fund is not obligated to sell a company's security simply because, subsequent to its purchase, the company's market capitalization has changed to be outside the capitalization range, if any, in effect for the fund.

The following are the names of the various entities involved with the fund's investment and business operations, along with brief descriptions of the role each entity performs.

The trustees oversee the fund's business activities and retain the services of the various firms that carry out the fund's operations.

John Hancock Advisers, LLC
601 Congress Street
Boston, MA 02210-2805

Founded in 1968, the advisor is a wholly owned subsidiary of John Hancock Life Insurance Company (U.S.A.), which in turn is a subsidiary of Manulife Financial Corporation.

The advisor's parent company has been helping individuals and institutions work toward their financial goals since 1862. The advisor offers investment solutions managed by leading institutional money managers, taking a disciplined team approach to portfolio management and research, leveraging the expertise of seasoned investment professionals. As of September 30, 2016, the advisor had total assets under management of approximately $136.5 billion.

Subject to general oversight by the Board of Trustees, the advisor manages and supervises the investment operations and business affairs of the fund. The advisor selects, contracts with and compensates one or more subadvisors to manage all or a portion of the fund's portfolio assets, subject to oversight by the advisor. In this role, the advisor has supervisory responsibility for managing the investment and reinvestment of the fund's portfolio assets through proactive oversight and monitoring of the subadvisor and the fund, as described in further detail below. The advisor is responsible for developing overall investment strategies for the fund and overseeing and implementing the fund's continuous investment programs and provides a variety of advisory oversight and investment research services. The advisor also provides management and transition services associated with certain fund events (e.g., strategy, portfolio manager or subadvisor changes) and coordinates and oversees services provided under other agreements.

The advisor has ultimate responsibility to oversee a subadvisor and recommend to the Board of Trustees its hiring, termination, and replacement. In this capacity, the advisor, among other things: (i) monitors on a daily basis the compliance of the subadvisor with the investment objectives and related policies of the fund; (ii) monitors significant changes that may impact the subadvisor's overall business and regularly performs due diligence reviews of the subadvisor; (iii) reviews the performance of the subadvisor; and (iv) reports periodically on such performance to the Board of Trustees. The advisor employs a team of investment professionals who provide these ongoing research and monitoring services.

The fund relies on an order from the Securities and Exchange Commission (SEC) permitting the advisor, subject to approval by the Board of Trustees, to appoint a subadvisor or change the terms of a subadvisory agreement without obtaining shareholder approval. The fund, therefore, is able to change subadvisors or the fees paid to a subadvisor, from time to time, without the expense and delays associated with obtaining shareholder approval of the change. This order does not, however, permit the advisor to appoint a subadvisor that is an affiliate of the advisor or the fund (other than by reason of serving as a subadvisor to the fund), or to increase the subadvisory fee of an affiliated subadvisor, without the approval of the shareholders.

The fund pays the advisor a management fee for its services to the fund. The advisor in turn pays the fees of the subadvisor. The management fee is stated as an annual percentage of the aggregate net assets of the fund (together with the assets of any other applicable fund identified in the advisory agreement)

determined in accordance with the following schedule, and that rate is applied to the average daily net assets of the fund.

During its most recent fiscal year, the fund paid the advisor a management fee equal to 0.70% of average daily net assets (including any waivers and/or reimbursements).

The basis for the Board of Trustees' approval of the advisory fees, and of the investment advisory agreement overall, including the subadvisory agreement, is discussed in the fund's most recent annual shareholder report for the period ended August 31.

The fund's annual operating expenses will likely vary throughout the period and from year to year. The fund's expenses for the current fiscal year may be higher than the expenses listed in the fund's Annual fund operating expenses table, for some of the following reasons: (i) a significant decrease in average net assets may result in a higher advisory fee rate if advisory fee breakpoints are not achieved; (ii) a significant decrease in average net assets may result in an increase in the expense ratio because certain fund expenses do not decrease as asset levels decrease; or (iii) fees may be incurred for extraordinary events such as fund tax expenses.

In addition to any expense waivers and/or reimbursement arrangements described in "Fund summary - Fees and expenses" on page 1 of this prospectus, the advisor has contractually agreed to waive a portion of its management fee and/or reimburse expenses for certain funds of the John Hancock funds complex, including the fund (the participating portfolios). The waiver equals, on an annualized basis, 0.0100% of that portion of the aggregate net assets of all the participating portfolios that exceeds $75 billion but is less than or equal to $125 billion; 0.0125% of that portion of the aggregate net assets of all the participating portfolios that exceeds $125 billion but is less than or equal to $150 billion; 0.0150% of that portion of the aggregate net assets of all the participating portfolios that exceeds $150 billion but is less than or equal to $175 billion; 0.0175% of that portion of the aggregate net assets of all the participating portfolios that exceeds $175 billion but is less than or equal to $200 billion; 0.0200% of that portion of the aggregate net assets of all the participating portfolios that exceeds $200 billion but is less than or equal to $225 billion; and 0.0225% of that portion of the aggregate net assets of all the participating portfolios that exceeds $225 billion. The amount of the reimbursement is calculated daily and allocated among all the participating portfolios in proportion to the daily net assets of each fund. This arrangement may be amended or terminated at any time by the advisor upon notice to the funds and with the approval of the Board of Trustees.

The advisor voluntarily agrees to reduce its management fee for the fund, or if necessary make payment to the fund, in an amount equal to the amount by which the expenses of the fund exceed 0.15% of the average net assets of the fund. For purposes of this agreement, "expenses of the fund" means all the expenses of the fund, excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (e) advisory fees, (f) class-specific expenses, (g) underlying fund expenses (acquired fund fees), and (h) short dividend expense. This agreement will continue in effect until terminated at any time by the advisor on notice to the fund.

The subadvisor handles the fund's portfolio management activities, subject to oversight by the advisor.

John Hancock Asset Management a division of Manulife Asset Management (US) LLC
197 Clarendon Street
Boston, MA 02116

The following are brief biographical profiles of the fund's portfolio managers. These managers are jointly and primarily responsible for the day-to-day management of the fund's portfolio. For more details about these individuals, including information about their compensation, other accounts they manage, and any investment they may have in the fund, see the SAI.

The custodian holds the fund's assets, settles all portfolio trades, and collects most of the valuation data required for calculating the fund's net asset value.

The principal distributor markets the fund and distributes shares through selling brokers, financial planners, and other financial representatives.

The transfer agent handles shareholder services, including recordkeeping and statements, distribution of dividends, and processing of buy-and-sell requests.

The fund has entered into contractual arrangements with various parties that provide services to the fund, including, among others, the advisor, subadvisor, custodian, principal distributor, and transfer agent, as described above and in the SAI. Fund shareholders are not parties to, or intended or "third-party" beneficiaries of, any of these contractual arrangements. These contractual arrangements are not intended to, nor do they, create in any individual shareholder or group of shareholders any right, either directly or on behalf of the fund, to either: (a) enforce such contracts against the service providers; or (b) seek any remedy under such contracts against the service providers.

This prospectus provides information concerning the fund that you should consider in determining whether to purchase shares of the fund. Each of this prospectus, the SAI, or any contract that is an exhibit to the fund's registration statement, is not intended to, nor does it, give rise to an agreement or contract between the fund and any investor. Each such document also does not give rise to any contract or create rights in any individual shareholder, group of shareholders, or other person, other than with respect to any rights conferred explicitly by federal or state securities laws that may not be waived.

These tables detail the financial performance of each share class described in this prospectus, including total return information showing how much an investment in the fund has increased or decreased each period (assuming reinvestment of all dividends and distributions). Certain information reflects financial results for a single fund share.

The financial statements of the fund as of August 31, 2016, have been audited by PricewaterhouseCoopers LLP (PwC), the fund's independent registered public accounting firm. The report of PwC, along with the fund's financial statements in the fund's annual report for the fiscal year ended August 31, 2016, has been incorporated by reference into the SAI. Copies of the fund's most recent annual report are available upon request.

Each share class has its own cost structure. Except for Class I and Class R6 shares, each share class has a Rule 12b-1 plan that allows it to pay fees for the sale, distribution, and service of its shares.

A front-end sales charge, as described in the section "How sales charges for Class A and Class C shares are calculated"

A 1.00% contingent deferred sales charge (CDSC) on shares sold within one year of purchase

No front-end or deferred sales charges; all your money goes to work for you right away

Rule 12b-1 fees of 0.15% (under the Rule 12b-1 plan, the distributor has the ability to collect 0.25%; however, the distributor has contractually agreed to waive 0.10% of these fees through December 31, 2017)

No front-end or deferred sales charges; all your money goes to work for you right away

Rule 12b-1 fees, if applicable, will be paid to the fund's distributor, John Hancock Funds, LLC, and may be used by the distributor for expenses relating to the sale, distribution of, and shareholder or administrative services for holders of, the shares of the class, and for the payment of service fees that come within Rule 2341 of the Conduct Rules of the Financial Industry Regulatory Authority (FINRA).

Because Rule 12b-1 fees are paid out of the fund's assets on an ongoing basis, over time they will increase the cost of your investment and may cost shareholders more than other types of sales charges.

Your broker-dealer or agent may charge you a fee to effect transactions in fund shares. Other share classes of the fund, which have their own expense structure, may be offered in separate prospectuses.

In addition to the Rule 12b-1 plans, the fund has adopted plans for Class R2 and Class R4 shares that authorize the fund to pay affiliated and unaffiliated entities a service fee for providing certain recordkeeping and other administrative services in connection with investments in the fund by retirement plans. The service fee is a specified percentage of the average daily net assets of the fund's share class held by plan participants and is up to 0.25% for Class R2 shares and 0.10% for Class R4 shares.

The performance and expense information included in this prospectus does not reflect fees and expenses of any plan that may use a fund as its underlying investment medium. If such fees and expenses had been reflected, performance would be lower.

Class A, Class C, Class R2, and Class R4 shares of the fund are primarily sold through financial intermediaries, such as brokers, banks, registered investment advisors, financial planners, and retirement plan administrators. These firms may be compensated for selling shares of the fund in two principal ways:

No dealer compensation is paid from fund assets on sales of Class R6 shares. Class R6 shares do not carry sales commissions, pay Rule 12b-1 fees, or make payments to financial intermediaries to assist in the distributor's efforts to promote the sale of the fund's shares. Neither the fund nor its affiliates make any type of administrative or service payments in connection with investments in Class R6 shares.

Except with respect to Class R6 shares, certain firms may request, and the distributor may agree to make, payments in addition to sales commissions and Rule 12b-1 fees, if applicable, out of the distributor's own resources.

These additional payments are sometimes referred to as revenue sharing. These payments assist in the distributor's efforts to promote the sale of the fund's shares. The distributor agrees with the firm on the methods for calculating any additional compensation, which may include the level of sales or assets attributable to the firm. Not all firms receive additional compensation, and the amount of compensation varies. These payments could be significant to a firm. The distributor determines which firms to support and the extent of the payments it is willing to make. The distributor generally chooses to compensate firms that have a strong capability to distribute shares of the fund and that are willing to cooperate with the distributor's promotional efforts.

The distributor hopes to benefit from revenue sharing by increasing the fund's net assets, which, as well as benefiting the fund, would result in additional management and other fees for the advisor and its affiliates. In consideration for revenue sharing, a firm may feature the fund in its sales system or give preferential access to members of its sales force or management. In addition, the firm may agree to participate in the distributor's marketing efforts by allowing the distributor or its affiliates to participate in conferences, seminars, or other programs attended by the intermediary's sales force. Although an

intermediary may seek revenue-sharing payments to offset costs incurred by the firm in servicing its clients who have invested in the fund, the intermediary may earn a profit on these payments. Revenue-sharing payments may provide your firm with an incentive to favor the fund.

The SAI discusses the distributor's revenue-sharing arrangements in more detail. Your intermediary may charge you additional fees other than those disclosed in this prospectus. You can ask your firm about any payments it receives from the distributor or the fund, as well as about fees and/or commissions it charges.

The distributor, advisor, and their affiliates may have other relationships with your firm relating to the provisions of services to the fund, such as providing omnibus account services, transaction-processing services, or effecting portfolio transactions for the fund. If your intermediary provides these services, the advisor or the fund may compensate the intermediary for these services. In addition, your intermediary may have other compensated relationships with the advisor or its affiliates that are not related to the fund.

The broker-dealer of record for a pension, profit-sharing, or other plan qualified under Section 401(a), or described in Section 457(b) of the Internal Revenue Code of 1986, as amended (the Code), that is funded by certain group annuity contracts issued by John Hancock insurance companies is eligible to receive ongoing compensation (rollover compensation) when a plan participant terminates from the qualified plan and rolls over assets into a John Hancock-sponsored custodial IRA or a John Hancock custodial Roth IRA invested in shares of John Hancock funds. The rollover compensation is paid from a fund's Rule 12b-1 fees to the plan's broker-dealer of record at an annual rate not expected to exceed 0.25% of the average daily net eligible assets held in John Hancock funds (0.15% for John Hancock Money Market Fund) under the rollover program. Rollover compensation is made in the first year and continues thereafter, quarterly in arrears. A John Hancock insurance company may also pay the third-party administrator for the plan a one-time nominal fee not expected to exceed $25 per participant rollover into a John Hancock fund for facilitating the transaction.

* Offering price is the net asset value per share plus any initial sales charge.

You may qualify for a reduced Class A sales charge if you own or are purchasing Class A, Class B, Class C, Class ADV, Class I, Class I2, Class R1, Class R2, Class R3, Class R4, Class R5, or Class R6 shares of a John Hancock open-end mutual fund. To receive the reduced sales charge, you must tell your broker or financial representative at the time you purchase the fund's Class A shares about any other John Hancock mutual funds held by you, your spouse, or your children under the age of 21. This includes investments held in an individual retirement account, in an employee benefit plan, or with a broker or financial representative other than the one handling your current purchase. John Hancock will credit the combined value, at the current offering price, of all eligible accounts to determine whether you qualify for a reduced sales charge on your current purchase. You may need to provide documentation for these accounts, such as an account statement. For more information about sales charges, reductions, and waivers, you may visit the fund's website at jhinvestments.com, which includes hyperlinks to facilitate access to this information. You may also consult your broker or financial advisor, or refer to the section entitled "Initial sales charge on Class A shares" in the fund's SAI. You may request an SAI from your broker or financial advisor by accessing the fund's website at jhinvestments.com or by calling Signature Services at 800-225-5291.

Class A shares are available with no front-end sales charge on investments of $1 million or more. There is a contingent deferred sales charge (CDSC) on any Class A shares upon which a commission or finder's fee was paid that are sold within one year of purchase, as follows:

For purposes of this CDSC, all purchases made during a calendar month are counted as having been made on the first day of that month.

The CDSC is based on the lesser of the original purchase cost or the current market value of the shares being sold, and is not charged on shares you acquired by reinvesting your dividends. To keep your CDSC as low as possible, each time you place a request to sell shares, we will first sell any shares in your account that are not subject to a CDSC.

Shares are offered at their net asset value per share, without any initial sales charge.

A CDSC may be charged if a commission has been paid and you sell Class C shares within a certain time after you bought them, as described in the table below. There is no CDSC on shares acquired through reinvestment of dividends. The CDSC is based on the original purchase cost or the current market value of the shares being sold, whichever is less. The CDSC is as follows:

For purposes of this CDSC, all purchases made during a calendar month are counted as having been made on the first day of that month.

To keep your CDSC as low as possible, each time you place a request to sell shares, we will first sell any shares in your account that carry no CDSC.

There are several ways you can combine multiple purchases of shares of John Hancock funds to take advantage of the breakpoints in the sales charge schedule. The first three ways can be combined in any manner.

Accumulation privilege—lets you add the value of any class of shares of any John Hancock open-end fund you already own to the amount of your next Class A investment for purposes of calculating the sales charge. However, Class A shares of money market funds will not qualify unless you have already paid a sales charge on those shares.

Letter of intention—lets you purchase Class A shares of a fund over a 13-month period and receive the same sales charge as if all shares had been purchased at once. You can use a letter of intention to qualify for reduced sales charges if you plan to invest at least to the first breakpoint level (generally $50,000 or $100,000 depending on the specific fund) in a John Hancock fund's Class A shares during the next 13 months. Completing a letter of intention does not obligate you to purchase additional shares. However, if you do not buy enough shares to qualify for the lower sales charges by the earlier of the end of the 13-month period or when you sell your shares, your sales charges will be recalculated to reflect your actual amount purchased. It is your responsibility to tell John Hancock Signature Services Inc. or your financial advisor when you believe you have purchased shares totaling an amount eligible for reduced sales charges, as stated in your letter of intention. Further information is provided in the SAI.

Combination privilege—lets you combine shares of all funds for purposes of calculating the Class A sales charge.

To utilize any reduction, you must complete the appropriate section of your application, or contact your financial representative or Signature Services. Consult the SAI for additional details (see the back cover of this prospectus).

A group may be treated as a single purchaser under the accumulation and combination privileges. Each investor has an individual account, but the group's investments are lumped together for sales charge purposes, making the investors potentially eligible for reduced sales charges. There is no charge or obligation to invest (although initial investments per account opened must satisfy minimum initial investment requirements specified in the section entitled "Opening an account"), and individual investors may close their accounts at any time.

To utilize this program, you must contact your financial representative or Signature Services to find out how to qualify. Consult the SAI for additional details (see the back cover of this prospectus).

As long as Signature Services is notified at the time you sell, any CDSC for Class A or Class C shares will be waived in the following cases, as applicable:

certain retirement plans participating in Merrill Lynch, The Princeton Retirement Group, Inc., or PruSolutions^SM programs

redemptions pursuant to the fund's right to liquidate an account that is below the minimum account value stated below in "Dividends and account policies," under the subsection "Small accounts"

redemptions of Class A shares made after one year from the inception of a retirement plan at John Hancock

rollovers, contract exchanges, or transfers of John Hancock custodial 403(b)(7) account assets required by John Hancock as a result of its decision to discontinue maintaining and administering 403(b)(7) accounts

To utilize a waiver, you must contact your financial representative or Signature Services. Consult the SAI for additional details (see the back cover of this prospectus).

If you sell shares of a John Hancock fund, you may reinvest some or all of the proceeds back into the same share class of the same fund and account from which it was removed, within 120 days without a sales charge, subject to fund minimums, as long as Signature Services or your financial representative is notified before you reinvest. If you paid a CDSC when you sold your shares, you will be credited with the amount of the CDSC. Consult the SAI for additional details.

To utilize this privilege, you must contact your financial representative or Signature Services. Consult the SAI for additional details (see the back cover of this prospectus).

In addition, this waiver does not apply to a group retirement plan that leaves its current recordkeeping arrangement and subsequently transacts business with the fund through a brokerage relationship in which sales charges are customarily imposed. Whether a sales charge waiver is available to your group retirement

plan through its record keeper depends upon the policies and procedures of your intermediary. Please consult your financial advisor for further information

Determine if you are eligible by referring to "Choosing an eligible share class."

Determine how much you want to invest. There is no minimum initial investment to purchase Class R2 or Class R4 shares. The minimum initial investments for Class A, Class C, Class I, and Class R6 shares are described below. There are no subsequent investment requirements for these share classes.

All Class A, Class C, Class I, and Class R6 shareholders must complete the account application, carefully following the instructions. If you have any questions, please contact your financial representative or call Signature Services at 800-225-5291 for Class A and Class C shares or 888-972-8696 for Class I and Class R6 shares.

Eligible retirement plans generally may open an account and purchase Class R2 or Class R4 shares by contacting any broker-dealer or other financial service firm authorized to sell Class R2 or Class R4 shares of the fund. Additional shares may be purchased through a retirement plan's administrator or recordkeeper.

For Class A and Class C shares, complete the appropriate parts of the account privileges application. By applying for privileges now, you can avoid

To help the government fight the funding of terrorism and money laundering activities, the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (USA PATRIOT Act) requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account.

For individual investors opening an account. When you open an account, you will be asked for your name, residential address, date of birth, and Social Security number.

For investors other than individuals. When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number (TIN), and you may be requested to provide information on persons with authority or control over the account, such as name, residential address, date of birth, and Social Security number. You may also be asked to provide documents, such as articles of incorporation, trust instruments, or partnership agreements, and other information that will help Signature Services identify the entity. Please see the mutual fund account application for more details.

Plan participants generally must contact their plan service provider to purchase, redeem, or exchange shares. The administrator of a retirement plan or employee benefits office can provide participants with detailed information on how to participate in the plan, elect a fund as an investment option, elect different investment options, alter the amounts contributed to the plan, or change allocations among investment options. For questions about participant accounts, participants should contact their employee benefits office, the plan administrator, or the organization that provides recordkeeping services for the plan.

Financial service firms may provide some of the shareholder servicing and account maintenance services required by retirement plan accounts and their plan participants, including transfers of registration, dividend payee changes, and generation of confirmation statements, and may arrange for plan administrators to provide other investment or administrative services. Financial service firms may charge retirement plans and plan participants transaction fees and/or other additional amounts for such services. Similarly, retirement plans may charge plan participants for certain expenses. These fees and additional amounts could reduce an investment return in the fund.

In certain circumstances, you will need to make your request to sell shares in writing. You may need to include additional items with your request, unless they were previously provided to Signature Services and are still accurate. These items are shown in the table below. You may also need to include a signature guarantee, which protects you against fraudulent orders. You will need a signature guarantee if:

you are selling more than $100,000 worth of shares (this requirement is waived for certain entities operating under a signed fax trading agreement with John Hancock), or

you are requesting payment other than by a check mailed to the address/bank of record and payable to the registered owner(s).

You will need to obtain your signature guarantee from a member of the Medallion Signature Guarantee Program. Most broker-dealers, banks, credit unions, and securities exchanges are members of this program. A notary public CANNOT provide a signature guarantee.

you are selling more than $100,000 worth of shares and are requesting payment by check (this requirement is waived for certain entities operating under a signed fax trading agreement with John Hancock);

you are selling more than $5 million worth of shares from the following types of accounts: custodial accounts held by banks, trust companies, or broker-dealers; endowments and foundations; corporate accounts; group retirement plans; and pension accounts (excluding IRAs, 403(b) plans, and all John Hancock custodial retirement accounts); or

you are requesting payment other than by a check mailed to the address/bank of record and payable to the registered owner(s).

The net asset value (NAV) for each class of shares of the fund is normally determined once daily as of the close of regular trading on the New York Stock Exchange (NYSE) (typically 4:00 P.M., Eastern time, on each business day that the NYSE is open). In case of emergency or other disruption resulting in the NYSE not opening for trading or the NYSE closing at a time other than the regularly scheduled close, the NAV may be determined as of the regularly scheduled close of the NYSE pursuant to the fund's Valuation Policies and Procedures. The time at which shares and transactions are priced and until which orders are accepted may vary to the extent permitted by the Securities and Exchange Commission and applicable regulations. On holidays or other days when the NYSE is closed, the NAV is not calculated and the fund does not transact purchase or redemption requests. Trading of securities that are primarily listed on foreign exchanges may take place on weekends and U.S. business holidays on which the fund's NAV is not calculated. Consequently, the fund's portfolio securities may trade and the NAV of the fund's shares may be significantly affected on days when a shareholder will not be able to purchase or redeem shares of the fund.

Each class of shares of the fund has its own NAV, which is computed by dividing the total assets, minus liabilities, allocated to each share class by the number of fund shares outstanding for that class. The current NAV of the fund is available on our website at jhinvestments.com.

Portfolio securities are valued by various methods that are generally described below. Portfolio securities also may be fair valued by the fund's Pricing Committee in certain instances pursuant to procedures established by the Trustees. Equity securities are generally valued at the last sale price or, for certain markets, the official closing price as of the close of the relevant exchange. Securities not traded on a particular day are valued using last available bid prices. A security that is listed or traded on more than one exchange is typically valued at the price on the exchange where the security was acquired or most likely will be sold. In certain instances, the Pricing Committee may determine to value equity securities using prices obtained from another exchange or market if trading on the exchange or market on which prices are typically obtained did not open for trading as scheduled, or if trading closed earlier than scheduled, and trading occurred as normal on another exchange or market. Debt obligations are valued based on evaluated prices provided by an independent pricing vendor. The value of securities denominated in foreign currencies is converted into U.S. dollars at the exchange rate supplied by an independent pricing vendor. Exchange-traded options are valued at the mean of the most recent bid and ask prices. Futures contracts are typically valued at settlement prices. If settlement prices are not available, futures contracts may be valued using last traded prices. Shares of other open-end investment companies that are not exchange-traded funds (underlying funds) are valued based on the NAVs of such underlying funds.

If market quotations or official closing prices are not readily available or are otherwise deemed unreliable because of market- or issuer-specific events, a security will be valued at its fair value as determined in good faith by the Trustees. The Trustees are assisted in their responsibility to fair value securities by the fund's Pricing Committee, and the actual calculation of a security's fair value may be made by the Pricing Committee acting pursuant to the procedures established by the Trustees. In certain instances, therefore, the Pricing Committee may determine that a reported valuation does not reflect fair value, based on additional information available or other factors, and may accordingly determine in good faith the fair value of the assets, which may differ from the reported valuation.

Fair value pricing of securities is intended to help ensure that a fund's NAV reflects the fair market value of the fund's portfolio securities as of the close of regular trading on the NYSE (as opposed to a value that no longer reflects market value as of such close), thus limiting the opportunity for aggressive traders or market timers to purchase shares of the fund at deflated prices reflecting stale security valuations and promptly sell such shares at a gain, thereby diluting the interests of long-term shareholders. However, a security's valuation may differ depending on the method used for determining value, and no assurance can be given that fair value pricing of securities will successfully eliminate all potential opportunities for such trading gains.

The use of fair value pricing has the effect of valuing a security based upon the price the fund might reasonably expect to receive if it sold that security in an orderly transaction between market participants, but does not guarantee that the security can be sold at the fair value price. Further, because of the inherent uncertainty and subjective nature of fair valuation, a fair valuation price may differ significantly from the value that would have been used had a readily available market price for the investment existed and these differences could be material.

Regarding the fund's investment in an underlying fund that is not an ETF, which (as noted above) is valued at such underlying fund's NAV, the prospectus for such underlying fund explains the circumstances and effects of fair value pricing for that underlying fund.

When you buy shares, you pay the NAV, plus any applicable sales charges, as described earlier. When you sell shares, you receive the NAV, minus any applicable deferred sales charges.

The fund is open on those days when the NYSE is open, typically Monday through Friday. Buy and sell requests are executed at the next NAV to be calculated after Signature Services receives your request in good order. In unusual circumstances, the fund has the right to redeem in kind.

At times of peak activity, it may be difficult to place requests by telephone, if available for your share class. During these times, consider using EASI-Line, accessing jhinvestments.com, or sending your request in writing.

In unusual circumstances, the fund may temporarily suspend the processing of sell requests or may postpone payment of proceeds for up to three business days or longer, as allowed by federal securities laws.

For your protection, telephone requests, if available for your share class, may be recorded in order to verify their accuracy. Also for your protection, telephone redemption transactions are not permitted on accounts in which names or mailing addresses have changed within the past 30 days. Proceeds from telephone transactions can only be mailed to the address of record.

You may exchange Class A and Class C shares of one John Hancock fund for shares of the same class of any other John Hancock fund that is then offering that class, generally without paying any sales charges, if applicable.

You may exchange Class I and Class R6 shares, respectively, of one John Hancock fund for Class I and Class R6 shares of any other John Hancock fund or for John Hancock Money Market Fund Class A shares.

You may exchange your Class R2 or Class R4 shares for shares of the same class of other John Hancock funds that are available through your plan, or John Hancock Money Market Fund Class A shares.

Note: Once exchanged into John Hancock Money Market Fund Class A shares, shares may only be exchanged back into the original class from which the shares were exchanged. As applicable, shares acquired in an exchange will be subject to the CDSC rate and holding schedule of the fund in which such shares were originally purchased if and when such shares are redeemed. For purposes of determining the holding period for calculating the CDSC, shares will continue to age from their original purchase date.

Provided the fund's eligibility requirements are met, an investor in the fund pursuant to a fee-based, wrap, or other investment platform program of certain firms, as determined by the fund, may be afforded an opportunity to make a conversion of Class A shares and/or Class C shares (not subject to a CDSC) also owned by the investor in the same fund to Class I shares of that fund.

In addition, (i) Trustees, (ii) employees of the advisor or its affiliates, and (iii) members of the fund's portfolio management team, may make a conversion of Class A shares also owned by the investor in the same fund to Class R6 shares or, if Class R6 shares are unavailable, Class I shares of that fund.

Conversion of Class A shares and/or Class C shares to Class I shares or Class R6 shares of the same fund in these particular circumstances does not cause the investor to recognize taxable gain or loss. For further details, see "Additional information concerning taxes" in the SAI for information regarding taxation upon the redemption or exchange of shares of the fund (see the back cover of this prospectus).

The fund may change or cancel its exchange policies at any time, upon 60 days' written notice to its shareholders. For further details, see "Additional services and programs" in the SAI (see the back cover of this prospectus).

The fund is intended for long-term investment purposes only and does not knowingly accept shareholders who engage in market timing or other types of excessive short-term trading. Short-term trading into and out of the fund can disrupt portfolio investment strategies and may increase fund expenses for all shareholders, including long-term shareholders who do not generate these costs.

Purchases and exchanges should be made primarily for investment purposes. The fund reserves the right to restrict, reject, or cancel (with respect to cancellations within one day of the order), for any reason and without any prior notice, any purchase or exchange order, including transactions representing excessive trading and transactions accepted by any shareholder's financial intermediary. For example, the fund may, in its discretion, restrict, reject, or cancel a purchase or exchange order even if the transaction is not subject to a specific limitation on exchange activity, as described below, if the fund or its agent determines that accepting the order could interfere with the efficient management of the fund's portfolio, or otherwise not be in the fund's best interest in light of unusual trading activity related to your account. In the event that the fund rejects or cancels an exchange request, neither the redemption nor the purchase side of the exchange will be processed. If you would like the redemption request to be processed even if the purchase order is rejected, you should submit separate redemption and purchase orders rather than placing an exchange order. The fund reserves the right to delay for up to one business day, consistent with applicable law, the processing of exchange requests in the event that, in the fund's judgment, such delay would be in the fund's best interest, in which case both the redemption and purchase side of the exchange will receive the fund's NAV at the conclusion of the delay period. The fund, through its agents in their sole discretion, may impose these remedial actions at the account holder level or the underlying shareholder level.

The Board of Trustees has adopted the following policies and procedures by which the fund, subject to the limitations described below, takes steps reasonably designed to curtail excessive trading practices.

The fund or its agent may reject or cancel a purchase order, suspend or terminate the exchange privilege, or terminate the ability of an investor to invest in John Hancock funds if the fund or its agent determines that a proposed transaction involves market timing or disruptive trading that it believes is likely to be detrimental to the fund. The fund or its agent cannot ensure that it will be able to identify all cases of market timing or disruptive trading, although it attempts to have adequate procedures in place to do so. The fund or its agent may also reject or cancel any purchase order (including an exchange) from an investor or group of investors for any other reason. Decisions to reject or cancel purchase orders (including exchanges) in the fund are inherently subjective and will be made in a manner believed to be in the best interest of the fund's shareholders. The fund does not have any arrangement to permit market timing or disruptive trading.

Exchanges made on the same day in the same account are aggregated for purposes of counting the number and dollar amount of exchanges made by the account holder. The exchange limits referenced above will not be imposed or may be modified under certain circumstances. For example, these exchange limits may be modified for accounts held by certain retirement plans to conform to plan exchange limits, ERISA considerations, or U.S. Department of Labor regulations. Certain automated or preestablished exchange, asset allocation, and dollar-cost-averaging programs are not subject to these exchange limits. These programs are excluded from the exchange limitation since the fund believes that they are advantageous to shareholders and do not offer an effective means for market timing or excessive trading strategies. These investment tools involve regular and predetermined purchase or redemption requests made well in advance of any knowledge of events affecting the market on the date of the purchase or redemption.

fund's shareholder accounts, and in light of the limitations on the ability of the fund to detect and curtail excessive trading practices, a significant percentage of the fund's shareholders may not be subject to the exchange limitation policy described above. In applying the exchange limitation policy, the fund considers information available to it at the time and reserves the right to consider trading activity in a single account or multiple accounts under common ownership, control, or influence.

Shareholders seeking to engage in excessive trading practices sometimes deploy a variety of strategies to avoid detection and, despite the efforts of the fund to prevent excessive trading, there is no guarantee that the fund or its agent will be able to identify such shareholders or curtail their trading practices. The ability of the fund and its agent to detect and curtail excessive trading practices may also be limited by operational systems and technological limitations. Because the fund will not always be able to detect frequent trading activity, investors should not assume that the fund will be able to detect or prevent all frequent trading or other practices that disadvantage the fund. For example, the ability of the fund to monitor trades that are placed by omnibus or other nominee accounts is severely limited in those instances in which the financial intermediary, including a financial advisor, broker, retirement plan administrator, or fee-based program sponsor, maintains the records of the fund's underlying beneficial owners. Omnibus or other nominee account arrangements are common forms of holding shares of the fund, particularly among certain financial intermediaries, such as financial advisors, brokers, retirement plan administrators, or fee-based program sponsors. These arrangements often permit the financial intermediary to aggregate its clients' transactions and ownership positions and do not identify the particular underlying shareholder(s) to the fund. However, the fund will work with financial intermediaries as necessary to discourage shareholders from engaging in abusive trading practices and to impose restrictions on excessive trades. In this regard, the fund has entered into information-sharing agreements with financial intermediaries pursuant to which these intermediaries are required to provide to the fund, at the fund's request, certain information relating to their customers investing in the fund through omnibus or other nominee accounts. The fund will use this information to attempt to identify excessive trading practices. Financial intermediaries are contractually required to follow any instructions from the fund to restrict or prohibit future purchases from shareholders that are found to have engaged in excessive trading in violation of the fund's policies. The fund cannot guarantee the accuracy of the information provided to it from financial intermediaries and so cannot ensure that it will be able to detect abusive trading practices that occur through omnibus or other nominee accounts. As a consequence, the fund's ability to monitor and discourage excessive trading practices in these types of accounts may be limited.

To the extent that the fund or its agent is unable to curtail excessive trading practices in the fund, these practices may interfere with the efficient management of the fund's portfolio and may result in the fund engaging in certain activities to a greater extent than it otherwise would, such as maintaining higher cash balances, using its line of credit, and engaging in increased portfolio transactions. Increased portfolio transactions and use of the line of credit would correspondingly increase the fund's operating costs and decrease the fund's investment performance. Maintenance of higher levels of cash balances would likewise result in lower fund investment performance during periods of rising markets.

While excessive trading can potentially occur in the fund, certain types of funds are more likely than others to be targets of excessive trading. For example:

A fund that invests a significant portion of its assets in small- or mid-capitalization stocks or securities in particular industries that may trade infrequently or are fair valued as discussed under "Valuation of securities" entails a greater risk of excessive trading, as investors may seek to trade fund shares in an effort to benefit from their understanding of the value of those types of securities (referred to as price arbitrage).

A fund that invests a material portion of its assets in securities of foreign issuers may be a potential target for excessive trading if investors seek to engage in price arbitrage based upon general trends in the securities markets that occur subsequent to the close of the primary market for such securities.

A fund that invests a significant portion of its assets in below-investment-grade (junk) bonds that may trade infrequently or are fair valued as discussed under "Valuation of securities" incurs a greater risk of excessive trading, as investors may seek to trade fund shares in an effort to benefit from their understanding of the value of those types of securities (referred to as price arbitrage).

Any frequent trading strategies may interfere with efficient management of a fund's portfolio and raise costs. A fund that invests in the types of securities discussed above may be exposed to this risk to a greater degree than a fund that invests in highly liquid securities. These risks would be less significant, for example, in a fund that primarily invests in U.S. government securities, money market instruments, investment-grade corporate issuers, or large-capitalization U.S. equity securities. Any successful price arbitrage may cause dilution in the value of the fund shares held by other shareholders.

The fund is required by law to obtain information for verifying an account holder's identity. For example, an individual will be required to supply his or her name, residential address, date of birth, and Social Security number. If you do not provide the required information, we may not be able to open your account. If verification is unsuccessful, the fund may close your account, redeem your shares at the next NAV, minus any applicable sales charges, and take any other steps that it deems reasonable.

When you place a request to sell shares for which the purchase money has not yet been collected, the request will be executed in a timely fashion, but the fund will not release the proceeds to you until your purchase payment clears. This may take up to 10 business days after the purchase.

For Class A and Class C shares, in general, you will receive account statements as follows:

after every transaction (except a dividend reinvestment, automatic investment, or systematic withdrawal) that affects your account balance

For Class I and Class R6 shares, in general, you will receive account statements as follows:

after every transaction (except a dividend reinvestment) that affects your account balance

For Class R2 and Class R4 shares, you will receive account statements from your plan's recordkeeper.

Every year you should also receive, if applicable, a Form 1099 tax information statement, mailed by February 15. For Class R2 and Class R4 shares, this information statement will be mailed by your plan's recordkeeper.

The fund generally declares dividends daily and pays them monthly. Capital gains, if any, are distributed annually, typically after the end of the fund's fiscal year. Most of the fund's dividends are income dividends. Your dividends begin accruing the day after the fund receives your investment and continue through the day your shares are actually sold.

Most investors have their dividends reinvested in additional shares of the same class of the same fund. If you choose this option, or if you do not indicate any choice, your dividends will be reinvested. Alternatively, you may choose to have your dividends and capital gains sent directly to your bank account or a check may be mailed if your combined dividend and capital gains amount is $10 or more. However, if the check is not deliverable or the combined dividend and capital gains amount is less than $10, your proceeds will be reinvested. If five or more of your dividend or capital gains checks remain uncashed after 180 days, all subsequent dividends and capital gains will be reinvested. No front-end sales charge or CDSC will be imposed on shares derived from reinvestment of dividends or capital gains distributions.

For investors who are not exempt from federal income taxes, dividends you receive from the fund, whether reinvested or taken as cash, are generally considered taxable. Dividends from the fund's short-term capital gains are taxable as ordinary income. Dividends from the fund's long-term capital gains are taxable at a lower rate. Whether gains are short term or long term depends on the fund's holding period. Some dividends paid in January may be taxable as if they had been paid the previous December.

The Form 1099 that is mailed to you every February, if applicable, details your dividends and their federal tax category, although you should verify your tax liability with your tax professional.

If the fund's distributions exceed its taxable income and capital gains realized during a taxable year, all or a portion of the distributions made in the same taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution will generally not be taxable, but will reduce each shareholder's cost basis in the fund and result in a higher reported capital gain or lower reported capital loss when those shares on which the distribution was received are sold.

Any time you sell or exchange shares, it is considered a taxable event for you if you are not exempt from federal income taxes. Depending on the purchase price and the sale price of the shares you sell or exchange, you may have a gain or a loss on the transaction. You are responsible for any tax liabilities generated by your transactions.

If the value of your account of Class A or Class C shares is less than $1,000, you may be asked to purchase more shares within 30 days. If you do not take action, the fund may close out your account and mail you the proceeds. Alternatively, the fund may charge you $20 a year to maintain your account. You will not be charged a CDSC if your account is closed for this reason.

MAAP lets you set up regular investments from paychecks or bank accounts to the John Hancock fund(s) to purchase Class A and Class C shares. Investors determine the frequency and amount of investments ($25 minimum per month), and they can terminate the program at any time. To establish, you must satisfy the minimum initial investment requirements specified in the section "Opening an account" and complete the appropriate parts of the account application.

This plan may be used for routine bill payments or periodic withdrawals from your account of Class A and Class C shares. To establish:

Make sure you are not planning to invest more money in this account (buying shares during a period when you are also selling shares of the same fund is not advantageous to you because of sales charges).

Specify the payee(s). The payee may be yourself or any other party, and there is no limit to the number of payees you may have, as long as they are all on the same payment schedule.

Determine the schedule: monthly, quarterly, semiannually, annually, or in certain selected months.

Fill out the relevant part of the account application. To add a systematic withdrawal plan to an existing account, contact your financial representative or Signature Services.

John Hancock funds offer a range of retirement plans, including Traditional and Roth IRAs, Coverdell ESAs, SIMPLE plans, and SEPs. Using these plans, you can invest in any John Hancock fund (except tax-free income funds). To find out more, call Signature Services at 800-225-5291.

This table describes the fees and expenses you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts on Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the John Hancock family of funds. More information about these and other discounts is available from your financial representative and on pages 18 to 19 of this prospectus under "Sales charge reductions and waivers" or pages 204 to 208 of the fund's Statement of Additional Information under "Initial sales charge on Class A shares."

2 The advisor contractually agrees to reduce its management fee or, if necessary, make payment to the fund, in an amount equal to the amount by which expenses of the fund exceed 0.89% of average net assets. For purposes of this agreement, "expenses of the fund" means all fund expenses, excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund's business, (e) class-specific expenses, (f) acquired fund fees and expenses paid indirectly, (g) borrowing costs, (h) prime brokerage fees, and (i) short dividend expense. This agreement expires on December 31, 2017, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

The fund seeks to generate capital appreciation by investing at least 80% of net assets (plus borrowings for investment purposes) in a diversified portfolio of equity securities. Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in securities of issuers domiciled outside of the United States, including in emerging markets. This includes securities of foreign issuers that trade on U.S. exchanges. Equity securities include common and preferred stocks and their equivalents, including depositary receipts, warrants, rights, and convertible securities. The fund may invest in securities of any market-capitalization.

The manager employs an unconstrained, bottom-up stock selection process based on fundamental research to attempt to identify undervalued companies that exhibit attractive valuations, solid business franchises, sustainable margins/cash flow, disciplined capital allocation, strong management teams, and strong balance sheets. The manager considers diversification benefits and liquidity of the security in making investment decisions.

The fund's main risks are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 5 of the prospectus.

Equity securities risk. The price of equity securities may decline due to changes in a company's financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential, and in certain markets value stocks may underperform the market as a whole.

Large company risk. Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.

Preferred and convertible securities risk. Unlike interest on debt securities, preferred stock dividends are payable only if declared by the issuer's board. Preferred stock may be subject to redemption provisions. The value of convertible preferred stock can depend heavily on the price of the underlying common stock.

Warrants risk. The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.

Class A shares commenced operations on May 16, 2013. Class C, Class R2, Class R4, and Class R6 shares commenced operations on March 27, 2015. Returns prior to a class's commencement date are those of Class A shares, except that they do not include sales charges and would be lower if they did. Returns for Class C, Class R2, Class R4, and Class R6 shares would have been substantially similar to returns of Class A shares because each share class is invested in the same portfolio of securities and returns would differ only to the extent that expenses of the classes are different.

Calendar year total returns (%)—Class A (sales charges are not reflected in the bar chart and returns would have been lower if they were)

Year-to-date total return. The fund's total return for the nine months ended September 30, 2016, was 7.39%.
Best quarter: Q2 '14, 4.26%
Worst quarter: Q3 '15, –7.76%

The Board of Trustees can change the fund's investment objective and strategies without shareholder approval.

The fund seeks to generate capital appreciation by investing at least 80% of net assets (plus borrowings for investment purposes) in a diversified portfolio of equity securities. This policy is subject to change only upon 60 days notice to shareholders. Under normal market conditions, at least 40% of the value of the fund's net assets will be invested in issuers domiciled outside of the United States, including in emerging markets, which includes securities for which the relevant reference entity is domiciled outside the United States, such as American Depositary Receipts (ADRs), that trade on U.S. exchanges. There are no limits on the market-capitalization ranges of the companies in which the fund may invest. The fund may invest in the securities of large, medium, or small companies.

In managing the fund, the manager seeks to identify undervalued companies that exhibit attractive valuations, solid business franchises, sustainable margins/cash flow, disciplined capital allocation, strong management teams, and strong balance sheets.

The manager employs an unconstrained, bottom-up stock selection process based on disciplined fundamental research with the aim to create a diversified portfolio of quality global stocks of any size that not only demonstrate compelling value but also generate sustainable cash flows. Equity securities include common and preferred stocks and their equivalents, including depositary receipts, warrants, rights, and securities convertible into common or preferred stocks.

The decision-making process involves candidate companies being screened for valuation, quality, and dividends, together with a detailed examination of the challenges and opportunities that exist for that business. The manager will assess the valuation opportunity for that company by establishing base-case, upside, and downside price targets. The manager will take into consideration the diversification benefits and the liquidity of the security before making the final investment decision.

The fund may invest in cash, money market instruments, repurchase agreements, or other short-term instruments for the purposes of meeting redemption requests or making other anticipated cash payments.

The fund may invest up to 100% of its assets in cash, money market instruments, repurchase agreements or other short-term instruments for the purpose of protecting the fund in the event the manager determines that market, economic, political or other conditions warrant a defensive posture.

To the extent that the fund is in a defensive position, its ability to achieve its investment objective will be limited.

Below are descriptions of the main factors that may play a role in shaping the fund's overall risk profile. The descriptions appear in alphabetical order, not in order of importance. For further details about fund risks, including additional risk factors that are not discussed in this prospectus because they are not considered primary factors, see the fund's Statement of Additional Information (SAI).

prime mortgage crisis in 2008; financial distress in the U.S. auto industry; credit and liquidity issues involving certain money market mutual funds; governmental efforts to limit short selling and high frequency trading; measures to address U.S. federal and state budget deficits; social, political, and economic instability in Europe; Standard & Poor's Ratings Services' downgrade of U.S. long-term sovereign debt; economic stimulus by the Japanese central bank; steep declines in oil prices; dramatic changes in currency exchange rates; and China's economic slowdown. Global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region might adversely impact issuers in a different country or region. Both domestic and foreign equity markets have experienced increased volatility and turmoil, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected, and it is uncertain when these conditions will recur. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

Common and preferred stocks represent equity ownership in a company. Stock markets are volatile. The price of equity securities will fluctuate, and can decline and reduce the value of a fund investing in equities. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. The value of equity securities purchased by a fund could decline if the financial condition of the companies in which the fund is invested declines, or if overall market and economic conditions deteriorate. An issuer's financial condition could decline as a result of poor management decisions, competitive pressures, technological obsolescence, undue reliance on suppliers, labor issues, shortages, corporate restructurings, fraudulent disclosures, or other factors. Changes in the financial condition of a single issuer can impact the market as a whole.

Even a fund that invests in high-quality, or blue chip, equity securities, or securities of established companies with large market capitalizations (which generally have strong financial characteristics), can be negatively impacted by poor overall market and economic conditions. Companies with large market capitalizations may also have less growth potential than smaller companies and may be less able to react quickly to changes in the marketplace.

The fund may maintain substantial exposure to equities and generally does not attempt to time the market. Because of this exposure, the possibility that stock market prices in general will decline over short or extended periods subjects the fund to unpredictable declines in the value of its investments, as well as periods of poor performance.

Value investing risk. Certain equity securities (generally referred to as value securities) are purchased primarily because they are selling at prices below what the manager believes to be their fundamental value and not necessarily because the issuing companies are expected to experience significant earnings growth. The fund bears the risk that the companies that issued these securities may not overcome the adverse business developments or other factors causing their securities to be perceived by the manager to be underpriced or that the market may never come to recognize their fundamental value. A value stock may not increase in price, as anticipated by the manager investing in such securities, if other investors fail to recognize the company's value and bid up the price or invest in markets favoring faster growing companies. The fund's strategy of investing in value stocks also carries the risk that in certain markets, value stocks will underperform growth stocks. In addition, securities issued by U.S. entities with substantial foreign operations may involve risks relating to economic, political or regulatory conditions in foreign countries.

taxes, higher custodial costs, and the possibility that foreign taxes will be charged on dividends and interest payable on foreign securities, some or all of which may not be reclaimable. Also, for lesser-developed countries, nationalization, expropriation, or confiscatory taxation; adverse changes in investment or exchange control regulations (which may include suspension of the ability to transfer currency or assets from a country); political changes; or diplomatic developments could adversely affect a fund's investments. In the event of nationalization, expropriation, or other confiscation, the fund could lose its entire investment in a foreign security. All funds that invest in foreign securities are subject to these risks. Some of the foreign risks are also applicable to funds that invest a material portion of their assets in securities of foreign issuers traded in the United States.

Emerging-market risk. Investments in the securities of issuers based in countries with emerging-market economies are subject to greater levels of foreign investment risk than investments in more-developed foreign markets, since emerging-market securities may present market, credit, currency, liquidity, legal, political, and other risks greater than, or in addition to, the risks of investing in developed foreign countries. These risks include high currency exchange-rate fluctuations; increased risk of default (including both government and private issuers); greater social, economic, and political uncertainty and instability (including the risk of war); more substantial governmental involvement in the economy; less governmental supervision and regulation of the securities markets and participants in those markets; controls on foreign investment and limitations on repatriation of invested capital and on a fund's ability to exchange local currencies for U.S. dollars; unavailability of currency hedging techniques in certain emerging-market countries; the fact that companies in emerging-market countries may be newly organized, smaller, and less seasoned; the difference in, or lack of, auditing and financial reporting standards, which may result in the unavailability of material information about issuers; different clearance and settlement procedures, which may be unable to keep pace with the volume of securities transactions or otherwise make it difficult to engage in such transactions; difficulties in obtaining and/or enforcing legal judgments in foreign jurisdictions; and significantly smaller market capitalizations of emerging-market issuers.

Currency risk. Currency risk is the risk that fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund's investments. Currency risk includes both the risk that currencies in which a fund's investments are traded, or currencies in which a fund has taken an active investment position, will decline in value relative to the U.S. dollar and, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly for a number of reasons, including the forces of supply and demand in the foreign exchange markets, actual or perceived changes in interest rates and intervention (or the failure to intervene) by U.S. or foreign governments or central banks, or by currency controls or political developments in the United States or abroad. Certain funds may also take active currency positions and may cross-hedge currency exposure represented by their securities into another foreign currency. This may result in a fund's currency exposure being substantially different than that suggested by its securities investments. All funds with foreign currency holdings and/or that invest or trade in securities denominated in foreign currencies or related derivative instruments may be adversely affected by changes in foreign currency exchange rates. Derivative foreign currency transactions (such as futures, forwards, and swaps) may also involve leveraging risk, in addition to currency risk. Leverage may disproportionately increase a fund's portfolio losses and reduce opportunities for gain when interest rates, stock prices, or currency rates are changing.

Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Many larger companies also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. For purposes of the fund's investment policies, the market capitalization of a company is based on its capitalization at the time the fund purchases the company's securities. Market capitalizations of companies change over time. The fund is not obligated to sell a company's security simply because, subsequent to its purchase, the company's market capitalization has changed to be outside the capitalization range, if any, in effect for the fund.

Unlike interest on debt securities, preferred stock dividends are payable only if declared by the issuer's board. Also, preferred stock may be subject to optional or mandatory redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. The value of convertible preferred stock can depend heavily upon the value of the security into which such convertible preferred stock is converted, depending on whether the market price of the underlying security exceeds the conversion price.

than those securities. They may also trade in the OTC market or on a regional exchange, or may otherwise have limited liquidity. Investments in less-seasoned companies with medium and smaller market capitalizations may not only present greater opportunities for growth and capital appreciation, but also involve greater risks than are customarily associated with more established companies with larger market capitalizations. These risks apply to all funds that invest in the securities of companies with smaller- or medium-sized market capitalizations. For purposes of the fund's investment policies, the market capitalization of a company is based on its capitalization at the time the fund purchases the company's securities. Market capitalizations of companies change over time. The fund is not obligated to sell a company's security simply because, subsequent to its purchase, the company's market capitalization has changed to be outside the capitalization range, if any, in effect for the fund.

Warrants are rights to purchase securities at specific prices and are valid for a specific period of time. Warrant prices do not necessarily move parallel to the prices of the underlying securities, and warrant holders receive no dividends and have no voting rights or rights with respect to the assets of an issuer. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants cease to have value if not exercised prior to the expiration date. These factors can make warrants more speculative than other types of investments.

The following are the names of the various entities involved with the fund's investment and business operations, along with brief descriptions of the role each entity performs.

The trustees oversee the fund's business activities and retain the services of the various firms that carry out the fund's operations.

John Hancock Advisers, LLC
601 Congress Street
Boston, MA 02210-2805

Founded in 1968, the advisor is a wholly owned subsidiary of John Hancock Life Insurance Company (U.S.A.), which in turn is a subsidiary of Manulife Financial Corporation.
